TYPE-WRITING MACHINE.

SPECIFICATION forming partof Letters Patent No. 357,090, dated February1, 1887.

Application filed August 19, 1885. Serial No. 174,819. A(No model.)

yTo all whom it may concern.-

Be it'J known that I, N. GRIER MOORE, a citizen ofthe Uni tedStates,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in TypeWriting Machines;and I do hereby declare the following to be such a full, clear,and exactdescription of the invention as will yenable others skilled in the artto which it appertains to makeand use the same.

This invention relates to that class of type writing machines in whichthe type or letters are secured to the periphery of a disk and thepaper-roller is caused by a movement ofa hand`lever to, oscillate andimpinge iagainst said type, anrdhas for itsobject the simplification ofthe various parts, hereinafter mentioned, so as to insure a more perfectmachine, exact in its every movement, producing 'as-little friction aspossible, and requiring the minimum of power by the operator.

My invention will be more fully understood by reference to theaccompanying drawings,

forming a part of this specification, and in which similar letters ofreference indicate like parts throughout the several figures.

In said drawings I have illustrated, in Figure 1,a plan view of amachine embodying my invention, at Fig. 2 a side elevation of the same,and at Fig. 3 a central vertical section thereof. At Fig. 4Ihaveillustrated the spacing device,*at Figs. 5 and 6 thedisengaginglatch to permit the return of the carriage, at Figs. 7 and 8the plate through which the inkribbon is laced, at Fig. 9 the device forrevolving the upper ribbon-reel, at Fig. l() the end of said reel,showing the locking-catch, at Fig. 11 a sectional view of theoperating-lever and latch for the index-wheel, and at Fig. 12 the mannerofinking the types when noribbon is employed.

In said drawings, the letter A represents the frame of the machine, andA the type disk or wheel loosely mounted on the hub ofan inclined table,a, so as to easily revolve thereon. This table is rigidly supportedabove and on the frame A by the supports or legs A2.

The type are secured to the edge of a ring, a',

which ring is placed on the type-disk A', and securely heldin positionby an annular ring, a2, secured by screws or other suitable means todifferent type-rings.

collar, a4.

said disk, and having a flange thereon which projects partially oversaid type-ring a. The type may be secured in any convenient manner tothe type-ring a'; but Iprefer to make 55 an electrotype strip containingall the required letters, numerals, &c., and secure said strip to theperiphery of the said ring a. Each Inaohine may be provided with severalsuch rings having different styles of type thereon, and the 6o.

change from one style of type'to another may be very quicklyaccomplished by simply removing the fiange-ring ai.

The inclined shaft A3 is round at the lower r and square at the upperend. The lower end is stepped in a bearing, as, in the frame of themachine, so as to move or slide therein. The upper square portion passesthrough an open ing in the table a and projects Aabove it so as topermit the non-revolving index or disk A* 7o to be secured thereon. thisdisk or index Af, I make the same number of letters, numerals, Src., asthere are type on the type-ring a. These characters may be Onthe upperface of indicated on the disk or may be printed on a removable paper ormetal ring, which could tit in an annular' recess in said disk, thenumber of index rings corresponding with the On the periphery oftheindex-disk A4, I providel a number of notches, 8o

equal to the greatest number of type or characters which any onetype-ring a may contain. These .notches are made of peculiar shape, asillustrated iu Fig. l, for the purpose hereinafter mentioned. 8 5

The shaft A3 is provided on its square portion below the disk A4 with acollar, a", having a ange at its lower edge. The operatinglever Bstraddles this collar, rests on the an'ge,

and is provided atfone end with the button b, 9c

Below the collar a4 95 j ated pawl, c, which engages with one end of thespacing-lever B'. This lever is pivoted, as shown in Fig. 4, so as topermit the pin's b2 and b3, with which it is provided,to engage thepinion B`-. A spring, b4, tends to keep the pin lf2-in engagement, asshown. 'Ihe collar c* is also provided with a groove or slot, al,

wherein the roller c, secured to one end of the carriage oscillati n glever C, may travel. This lever Cl is pivoted at c' to the frame, and atc2 it engages the rod c:s of the carriage. The end of the lever C may bebifurcated so as to straddle the rod e3,- or it may be provided with ayoke or clip,as shown. The carriageframe is supported byfriction-rollers at the rear on the guideway C, supported on. the frameA by means ot' brackets, and its front cud is supported on the rod I,which is secured to the frame by standardsv I. At the front end of thecarriage is hinged the rack-bar C2, which meshes with the spacing-wheelC3. The wheel Ca is only revolved one notch or tooth at a time, as willhereinafter lnore fully appear, and causes the rack-bar C2 and carriageC8 to travel longitudinally across the machine, as desired.

The pinion B2 and spacing-wheel C3 are mounted on opposite ends of theshaft b5, as shown in Figs. 2 and 3, at right angles to the path of thecarriage. As the spacing-lever B' is moved either by the operator or bythe upward movement of the collar a* the piu b2 thereon disengages fromthe pinion B2, while the pin b3 enters a space between two of the teethof said pinion. A tension device causes the rackbar C2 to revolve thespacing-wheel C3, thus communicating motion tothe pinion B2 through theshaft b5. As the operator ieleases the lever B the spring underneath thesameraises the lever and forces the pin b'into the next space on thepinion B2 as the latter is revolving. This will lock the pinion again.When the shaft A is raised, the pawl a6 on the collar a* is forced byits spring to and -agaiust the curved arm of the spacing-lever,

and thereby forces said end over in the direction indicated by thearrow, engaging the pin b3 and disengaging the pin b2. 'Ihe lever isreturned, as previously explained.v

At each end of the carriage I pivot a bellcrank lever, C, between theshort arms of which is mounted the rod c, hereiubefore mentioned. Theother arms of the levers support the paper-roll C5 and are connectedy bythe bar 0*. The paper is fed by hand to the roller iu the usual mannerfrom the bottom` and soon engages with the friction-roller CG. rIhisroller C is as long as the paper-roller, and is held so as to easilyrevolve by Hat spring-arms Clparallel to and against the paper-rollcr,as shown. To move the carriage rapidly or to return the carriage to thepoint of beginning, it is only necessary to disengage the rack-bar C2from the wheel C3. This is accomplished by means of the thumb-latch orlever D', pivoted to the carriage and having a tongue orlip, d, beneaththe end of said bar C2.

A spring, d', pressing on the lip d, may assist to keep the latch in itsnormal position, as illustrated in Fig. 5.

Beneath the carriage, at about the center, I secure one end of the cordD2. This cord after passing over a pulley, d2, secured to the frame A,is secured to4 the long end of the lever E. This lever is pivotedbeneath the frame near the front end, and the short arm is attached toone end of a tension-spring, E, while the other end of said spring issecured to the adjusting-serew 2. The lengths of the arms of this leverE and the position of. the spring with relation thereto are illustratedsubstantially in the drawings lin Fig. l, and are such as to cause asteady tension on the carriage through the length of its travel. In theposition illustrated the spring is extended and exerts its maximum ofstrain, and when the carriage is moved farther to the left of theoperator the spring contracts, and the loss of its tension iscompensated by the gain in leverage.

The paper-roll is turned so as to present a new line to the type by thefollowing means: A trip-lever, D3, is pivoted to one of the levers C,preferably at the lethand side, so as to be near the thumb-latch D', andcarries on its long arm a pawl, d, and spring. The spring d* keeps thepawl d in engagement with cir- Y cumferential ratchet-teeth on the endon the paper-roll C5. Stops d (ZT are provided on the lever-arm C* aboveand below the trip-lever D, the lower one being made adj ustable,so asto regulate the throw of the trip-lever D3. A spring, d5, tends to keepthe trip-lever in position, as shown in Fig. 2.

The type are inked in the usual manner either by an ink-ribbon or by anink-roller. When the roller is used, I prefer to employ the mechanismillustrated in Fig. 12. This consists in mounting the ink-rollerniovably in the end of a lever, F, which lever F is operated from therod c of the carriagc,as shown in dotted lines in said figure. The leverF is supported from the main frame A by aproper bracket. When theink-ribbon is used,lprc fer to lace the ribbon through slots in a plate,F', to secure proper tension on the ribbon. This plate F is held infront of the type about to be used and between it and the paper-roll,and may be supported from the frame, or, as I have shown, from the tablea by means of brackets.

In order to prevent more than one type from impinging against the paperwhen the paperroll is brought up against the typewheel, I provide saidplate F with a cross-bar, f, having an opening, f, which is only largeenough to permit one type to pass through it. The ribbonspools aremounted on shafts secured in a frame and supported from the mainframe A.The ribbon is automatically passed from one spool to the other, asfollows: Integral with or secured to each ribbonspool is abarrel-pinion, G, as long as the ink-ribbon is wide. These pinions, aswell as the spools, are loose IOO IIO

IZO

on their shafts so as to be moved lengthwise thereon. The shafts areprovided with a number of annular notches or grooves, into which iit thespring-dogs g, pivoted on the end of the 'spool or pinion.

, The ribbon may be moved from side to side, so as to use every portionthereof by simply lifting the dogs g from the notches and sliding thespool and pinion longitudinally o n the shaft and then dropping the dogsg again into another notch. Pivotedto the spool-holding `frame and belowthe spool is the arm G, which carries the pawl g. The pawl engages withthe teeth of the barrel-pinion G on one side, while the spring g2,secured to the frame, is provided withla curved end, so as to engage twoteeth of said -pinion at the same time, as shown in Fig. 9. 'Vlien thepaper-roller is tilted forward, as shown in dotted lines in said figure,a spring, g3, pressing on the arm G', forces said arm downward andcarries the hinged pawl gaway from one tooth of the pinion over againstanother tooth, the spring g2 preventing any tendency of the pinion torevolve. As thelpaper-roller returns after strikingthe type, thecross-bar c4 engages the arm G andy forces it'back to its normalposition, as shown in full lines in said Fig. 9, and at the same timethe pawl g revolves the barrel-pinion against the pressure of thefspringg2. Th us the ribbon is automatically wound around the upper spool,presenting afresh ink-surface to the' type at each stroke. The lowerribbonspool is precisely the saine in construction as the upper one7 butthe operating pawl is hinged to one end of the lever G2, which ispivoted to a bracket secured on the main frame v A. The other end ofthis lever G2 engages the rod c3. When the ribbon is being wound on theupper-spool I throw the lower pawl out of engagement, as indicated inFigs. 2 and 3, and when the ribbon is to be wound on the lower spool Iengage the lower pawl and disengage' the upper pawl. Then each movementforward of the paper-roller lowers, through Vthe rod c3, the forward orpawl end of thelever G2, and the ribbon-spool is revolved ou the returnmovement thereof. Y

The device illustrated in Fig. 1l. is for the purpose of locking thetype-disk in position during the printing of the letter or character,and consists of abent locking-lever, H, pivoted to the revolvingtype-disk. A spring, H4, on

said disk tends to keep one arm, H', of said lever up against theunderside ofthe operat- -ing-lever B. The other arm, H2, extends disk isshapedas shown in Fig. l, so as to pre- Sent an inclined portion oneither side. When the shaft A3.

the portion h enteringA said disk between two teeth, thus lockingthetype-disk to the indexdisk. When, the operating-lever is movedfarther downward, in order to make an impression, the index-disk is ofcourse `movedy downward with the shaft, the portion h being now parallelto the sides of the teeth of said wheel, and permitting the wheel toslide thereon while remainingloeked with the type-disk. A slot oropening, h2, is made in the operatinglever, to permit the bent end ofthe lever H to enter at this time. Pulleys i on each end and beneathrthe roller C5 are secured to the arms C4, and running from thesepulleys over pulleys on the ends of the friction-roller C6, are tapes orendless bands z".

The operation of myinvention is as follows: The-carriage' .being at theright-hand side of the machine, as shown in Fig. l, and theinkribbon'and device for operating the same being placed in position, Itake a sheet of paper to be printed upon and feed the same in beneaththe roller C5 until the paper is caught by the roller G6. I then takehold of the operating-lever B and turn it around until the index-pointis opposite the letter indicated on the `index-disk which I desire toprint on the paper. The operating-lever, being hinged to the type-disk,as explained, causes the said disk to revolve with it. The index-disk,the

type-disk, and the operating-lever are so arranged and adjusted withrelation to each other and to the shaft A3 that whenever said lever isrevolved around -the circumference of the non-rotating index disk to anypoint the same movement also causes the type-wheel to revolve, so as topresent to the opening the type which is indicated or marked on theindexdisk at the `point where the operating-lever is brought to a halt.By pressing down on the lever the shaft A3 is moved downward, and thusthe paper-roller is oscillated by means of IOO the lever O andconnections heretofore pointed out, and before the paper-roll strikesthe type the arm or dog H2 has securely locked the type-disk. It will beobserved that the power applied" by the operator to the lever is onlysuch as is required to overcome the force of the spring aiand to tiltthe paper-rollerforward to impinge against the type to makeanimpression.-

Now the operator may relax his pressure on the lever and the rest of thework is performed automatically-that is to say, on thereturn movement ofthe shaft caused by the spring a?, the entire carriage is caused to movelongitudinally the space of one-type through the medium of the rack C2,spacing-wheel B, pinion C3, lever B, and pawl uson the collar a4 on rIhespring H* beneath the arm H forces the dog orlatch H2 out of engagementwith the index-disk, and the ribbonspool is revolved ashortdistance, asexplained.

IIS

The operating-lever is then swung around the index-wheel to the nextletter pressed down, and so on, till the end of the line has beenreached on the paper. The thumb-latch D is then pressed downward, therack-bar disengaged thereby from the spacing-wheel C3. and the carriagemoved back tothe right-hand Yside ofthe machine against the pressure ofthe form shown in Li'or thc purpose et' insurg ing the perfect workingof the locking-lever g H. The sides of the teeth of the disk are bcveledand the front of the lever III bei ng pointed,

Ait will be seen that the lever will enter between two of the teethofthe disk A* and bring the type-disk A to the proper position thereby.

The index or pointer Jis pivoted to the operatinglevcr at a point wherethe lever is connected with the collar a, so that it will move up ordown with the index-disk A4, and at the same time when the lever isrevolved on the collar fri the pointer J will also revolve with The endofthe index J is slotted, so as to permit the locking-lever H to passthrough itand cuter between two of the teeth of the index-disk A4. Ifthe pointer J is rigidly secured to the lever B, the bent portion whichpasses around the edge of the disk A" should be extended above said disksufficiently to -clear it when the lever is pressed downward; but Iprefer to pivot or hinge the pointer, as Shown.

For the purpose of ready adjustment the pawl en may be attached to anindependent collar, so that the throw of the papcr-roller may be alteredwithout altering the spacing device.

For the purpose of regulating the blow of the paper roller or platenagainst the types and to make the impression even, I attach buffers K,with'cushions or springs 7U at the faces in such a position as toreceive a portion of the blow when the roller is oseillated for thepurpose of printing. In a former ap,- plication for patent uponimprovements in the same class of machines in which the type are inkedonly by a roller, I showed buffers for a like purpose attached to thestationary hub of the type-disk. 'lhe present improvement contemplatescspceially the use of ribbon-inkers, one of the objects being to enableit to mani fold in printing. In the position shown in the fermerapplication the buffers impress themselves through the carbon-paper usedin manifolding, and mal-:e the duplicates illegible. For this purpose Iattach the buffers K to the carriage, and in two forms, one attached soas to receive the stroke of the long arms C of the bell-crank leverscarrying the paper-roller,

and the other receiving the the short arm.

The buffers are made adjustable by aslot in the .short arm, set iuposition by a thumb 0r set screw, the buffers being pivotcd loosely tothe frame. I do not wish to limit myself, how ever, to suchconstruction, as other modifications for producing the same result willreadily suggest themselves to those skilled in the art to which thisinvention relates, land which may be used without departing from thespirit of my invention.

The inking device illustrated in Fig. 12 may be used with greatadvantage in this class of type-writing machines; but I do not hereinclaim such device, and any claim or claims thereon to which I may beentitled are hereby expressly reserved for another application.

The type-ring a', it will be observed, is made so as to be easilyremoved when it is desired te change the style of type used. The typemay be of any suitablemetal or hard rubber that will permit of its beingbent around the periphery 0R the ring a. This ring may be secured inplace on the disk A by the flangering a2, or may be retained in positionby simply iittiiig snugly over a shoulder or recess formed or turned onthe disk, and perhaps a pin holding it in place, so as to prevent itsbeing turned around on the disk A.

That I claim as my invention, and desirelto secure by Letters Patent, isas followsi l. Ina type-writing machine, a disk mov ably secured to theframe ofthe machine and provided on its periphery with type, anindexdisk rigidly secured above said type-disk to a non-rotating shaft,and a lever hinged at one end tothe type-disk and-loosely encirclingsaid shaft between the index-disk and the typedisk, whereby the lattermay be'revolved by said lever, substantially as and for the purposespecified.
